NAIL-MAKING MACHINE.

Application filed February 21, 1921. Serial No. 446,656.

This invention relates to strip feeding mechanism and is herein illustrated and described as embodied in a nail making machin-ein which the nails are cut from blanks successively fed to the cutting dies thereof.

An application for Letters Patent, Serial No.` 169,562. filed May 18, 1917, by George Goddu, for blank feeding mechanism. which has issued as Patent No. 1396191` granted Nov. 8. 1921, discloses mechanism for feedingr strips to a nail making machine vcomprising a 'carrier for presenting the strips .to the machine and means controlled by a strip in the carrier for automatically supplying One of the objects of the present invention is to provide improved and simplified mechanism of the same general character as that forming the subjectmatter of that application.

Vith this and other objects in view, a feature of the invention comprises novel means for feeding a nail strip towards nail severing position either with or without mechanism rendered operative by the passing of the strip out of contact` with a suitably arranged feeler to supply a new blank to the feeding means.

Another feature of the invention comprises a novel combination comprising a feed dog normally out of gripping engagement with the nail blank and means for moving the feed dog into and out of gripping relation to the blank at the commencement and conclusion respectively of each feeding movement thereof. In the illustrated machine this feed dog is mounted upon an oscillating` lever fulcrumed upon a rotary carrier and. is provided with cam portion arranged, as the carrier rotates, to be wiped by a cam roll, first to move the dog into gripping engagement with the nail strip and then to oscillate the 'lever to feed the nail. strip a stepforward toward the cutting dies. At the conclusion of the feeding movement the cam of the feed dog passes from the roll and the dog is moved back out of gripping relation to the nail strip for the return movement of the oscillating lever.

A further feature of the invention consists of simplified mechanism by which the passage of a nailV strip from an appropriate as long as a nail strip lies between thefeeler and the control finger. When, however, the nail strip passes from that position the feeler rocks about its pivot, swinging the end thereof' into such position that it is operative to rock the first wiper into position to cause the throwing in of a clutch which controls the transfer device and thus initiates supply of a fresh nail strip to' the feedingmeans. Further movement of the feeler brings it into engagement with the second wiper which results in moving the point of the feeler around theend of thev control finger to the other sid-e thereof against the 'action of al springv which normallyholds it in -contact with the nail strip. In' this position it is held by the control finger sothat its path of movement is such that it can pass by the first wiper during continued operation of the machine'without movement'thereof. The same movement of the second wiper which thus operates to shift the feeler is utilized to throw, 'or toinsure the throwing of, the clutch into inoperative condition to prevent the continuous repeated operation of the transfer device or, indeed, any operation thereof subsequent to th-e first untilafter the feeler has been moved to its normal, nail strip engaging position by the supplying of a fresh nail strip to the feeding mechanism.

TWith these and other objects and features in view the invention will now be described in connection with the accompanying drawings, which show an Villustrative embodiment therof, andpointed out in the appended claims.

In the drawings,

Fig. l is a side elevation of a machine embodying this invention;

Fig. 2 is a plan view of the strip feeding mechanism showing' also a portionA of the magazine from which the strips are supplied;

Fig. 3 is a perspective view, partly broken away better to disclose the construction ot the strip feeding mechanism;

Figs. 4 and 5 are similar side elevations partly broken away and showing two (litterent positions ot the toeler and its associated parts;

Fig. 6 is an elevational view olt the adjacent ends oit the ieeler, control tinger and feed dogs showing their pusition immediately ater the passing ot a strip 'from the feeding mechanism;

Fig. 7 is an exploded view ol" a clutch which may be utilized to operate the magazine and transfer mecl'ianism.

The villustrated machine is provided with a frame 2 upon which is mounted a head 4 carrying mechanism for operating upon a nail strip which, as shown, includes cutting dies 6 reciprocated by a cani shatt 8 past the edge oit' a. stationary anvil 10. The nail strip is presented to the cutting dies by a rotary carrier 12. the main casting 1.4- ot which is fulcrumed at 16 to a yoke 1S upstanding from a trame 2O.y this frame being preferably attached to the trame 2 in such manner that it is universally adjustable about the cutting dies as a center. The carrier 12 is shown as provided with tight and loose sprockets 22 and 24, the former being rotated by a chain 26 driven from the shat't 28 rendered flexible by universal joints 30 or other suitable means to permit adjustment of the frame 20 Without cramping that shaft. The shaft 28 is driven 'from the cam shaft 8 by suitable gearing including a pair of elliptical gears so arranged as to cause the velocity ot' rotation of the carrier 12 to be at a minimum when the strip is horizontal and the cutting` dies are operating to sever a nail therefrom and to be at a maximum when the strip is vertical in its movement from one nail severing position to thc neXt.

Gears 22 and 24 are connected by a clutch mechanism illustrated in Fig. 7 and consisting of two main clutch members rigidly carried by sprockets 22 and 24 respectively and a pawl. 34 arranged, when in one position, to connect the clutch members so as to render the clutch operative, and when in another position7 to disconnect the clutch members so that the clutch sh all be inoperative to cause movement ot the parts driven therefrom. When this pawl 34 is in the position indicated in Fig. 3 thD clutch members are disconnected but when the pawl is permitted to drop from that position it becomes operative to connect the two parts ot the clutch so that the gear 24 is positively rotated. Passing over sprocket 24 is a chain 36 which, when driven, is operative through suitable mechanism to rotate the magazine, as by a Geneva gear 38, and to oscillate a lever 40 connected by a link 42 with a transfer meniber 44 slidably carried upon a rod 46. Oscillation ot' the lever 40 trom the position shown in F 1 to the rightand back again results in transferring a nail strip from the magazine to the carrier l2.

rlhe structure so far described is not claimed to be novel with applicant. being substantially that set forth iu the United States Letters Patent No. 1,396,191, granted on the application of George Goddu hereinbetere referred to, to which patent reference may be had for a fuller description thereof.

The rotary carrier 12 includes a'frame 5l) journaled in suitable bearings 52 and is provided with a passage 54 (Fig. 3), through which nail strips 56 may be successively passed. Fulcrumed at 58 upon the carrier 50 is a lever 60 normally held towards the right, as viewed in Figs. 4 and 5, by a spring` 62, ll/lounted upon lever 60 is a fixed 'iced dog 64 and pivot-ally carried by that lever is a movable feed dog 66 provided with a spring G8 tending to hold it away 'troni ther nail strip and against a stop 7l). The end ot thisdog remote trom the nail strip is termed as a cam 72 (see Fig. 3) arranged, as the carrier is rotated, for wiping- Contact with rolls y74. 76 adjust-ably carried by a yolre 77 mounted upon the casting 14. Thus dog 6G is moved into gripping engagement with the nail strip and lever 60 and the two dogs are oscillated to teed the nail strip to the nail making machine. The end of the lever 60 is shaped, as shown at 78, to form a continuation ot cam 72 to insure the easy return ot the lever after each feeding movement thereof.

From the foregoing, it will be clear that as the carrier 12 rotates the cani end 72 otl feed dog 66 will repeatedly wipe the rolls 74 and 76 and that at each such impact that, dog will be moved into gripping engagement with the nail strip which will thus be pinched between the two dogs and will be held so pinched during its feeding movement. At the conclusion ot' each tecding movement thusV produced the cain ond ot dog G6 will pass from the roll 74 or 76 and, as cam 78 passes by the roll, lever (i0 will be returned by spring 62 to its normal position, dog` 66 at this time beine' held out ot gripping engagement with the nail strip by its spring 68.

To accomplish the transiter ot successive nail strips Jfrom the magazine to the feeding device a teeler 8O is provided. pivoted at 82 to the frame 50 oit the carrier, a compression spring 84 being operative normally to hold the eelcr in engagement with the nail strip. The end 86 ot the teeler remote from the nail strip is positioned normally to pass by without moving a pair ot' wipers 88 and 90 (Fig, 3) rigidly mounted upon one end of a rock sha-ft 92, the other end of which carries a dog 94 normally interposed in the path of movement of pawl 34 to prevent the operation of the clutch A torsion spring 96 tends to move dog 94 into the position indicated in Fig. 3, its further movement towards the clutch being prevented by stops 98.

Adjacent tothe feeler 8O and normally, as shown in Figs. 3 and 4, on the opposite side of the nail strip theiefrom is a control finger 100 pivoted at 102 to the frame 50 and provided with a spring 104 tendingto move it in a counter 'clockwise direction, as viewed in Fig. 4 against a stop 106.

Upon the passage of a nail strip out of engagement with the end of the feelei 89,

the feelei under the influence vof the spring- 84 assumes the position shownin Fig. In this position its end 86 during the rotation of the carrier presently engages wiper SS,

vrocking it and the dog 94 in a clockwise direction, as viewed in Fig. and thus removing dog 94 from the position shown in that figure in which it restrains pawl 34. The clutch is thus rendered operative to move` the transfer member 44 to the right as viewed in Fig. l, to rotate the magazine a` step, and then to move the transfer member 44 back to push a nail strip from the magazine into the carrier l2. The shape and location of feeler 8() is such that the incoming end of the nail strip forces it from the position of Fig. 6 back to that of Fig. 4 and the feeding operation continues in its normallfashion until that nail strip passes beyond the feelei.

If, for any reason, such as an empty magafeelei' 8O through a small angle in a counterl clockwise direction, as viewed in Fig. 5, to such an extent that the end thereof adjacent to the nail strip moves to the left of the controlling linger 100, as viewed in Figs. 4 and 5, until it assumes the position of Fig. 5. 'ln this position it is held by the control finger 100 with its end 86 in such position that, during further rot-ation of the carrier, it passes by wiper S8 without engagement therewith. Continued, repeated operation of the transfer device is thus prevented. At the saine time, the parts are in such condition that, upon the supplying of another nail strip to the feeding mechanism," the fresh nail strip may pass between the-ends of feeler 8O and the control linger 100 so as to force those members into their usual posivtion and to permit the nail strip to be fed to 0rip and feed a` nail strip step by step' n toward the cutting dies, said feed dog being normally out of gripping engagement with the nail strip being fed, a magazineA constructed to hold ayplurality of the nail strips, and a transfer device to` feed they nail strips successively from the magazine to the carrier. l
